Electricity

Division 2

In Division 2, the world of metrology rotates around the "electrical triangle" of volt, ohm and ampere - from high-frequency and energy measuring technology to quantum electronics.

Tasks

Electrical quantities are ubiquitous in metrology. The Electricity Division is charged with the realization and dissemination of the electrical and magnetic units. To this end, the Electricity Division develops precision electromagnetic measurements, which are based on electrical quantum metrology and quantum standards nowadays. Nanotechnology is employed and advanced for the in-house fabrication of superconductor and semiconductor quantum standards. Fundamental studies of quantum effects in condensed matter lay the groundwork for the electrical metrology of the future.


The Electricity Division offers various calibration services (see Calibration and Measurement Capabilities) and advises governmental authorities, standardization organizations, and industry on electrical measurements. Knowledge transfer programs support innovation and economic growth.

Im Rahmen des von der PTB koordinierten Europäischen Forschungsprojekts „NanoMag“ wurden verschiedene Kalibrierverfahren zur Rückführung magnetischer Feldmessungen mit Ortsauflösung von einigen zehn Nanometern miteinander verglichen und validiert. Die Ergebnisse dieser Forschungsarbeiten wurden kürzlich in der angesehenen Fachzeitschrift „Small“ publiziert.

The first General Meeting of the European Metrology Network on Quantum Technologies (EMN-Q) was held on 15 October 2019 in Berlin. Main targets of the network, in which PTB is involved in operational and executive functions, is the coordination of metrological activities in quantum technology and their strategic development in Europe, oriented to the needs of relevant stakeholder groups.
